Whatever happened to Persephone?

I remembered a few minutes ago that it had been a while since we had a new chapter for Goddess' Tears, so sauntered over to Persephone's author page to find out more...

...only to find that only the title pages for her stories (Frozen Balance, Goddess' Tears, Healing Dagger) remain, and all the story content appears to have been pulled. I don't recall reading any blog entries announcing her departure, so does anyone know what happened?
